SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 484,671, dated October18, 1892.

Application filed September 25,1888. Serial No. 286,327. (No model.)

T to whom it may concern.-

Be it known that 1, JOHN REEOE, of Boston, county of Suffolk, State ofMassachusetts, have invented an Improvement in Sewing- Machines, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention has for its object to improve the construction of themachine described in my application, Serial No. 248,827, filed September5, 1887. In the said application the needle-bar is shown as arranged toreciprocate in a vertical plane, the shuttle is a straight reciprocatingshuttle, and the feed is arranged above the bed-plate and the guide isprojected above the bed-plate, and the work-holder is arranged toreciprocate horizontally, while the thrum ends and stay-cord are securedto the material. In this embodiment of my invention the needle-bar isarranged to reciprocate horizontally below the bed-plate, theWork-holder is arranged to reciprocate vertically with relation to thebedplate, and theguide is so placed as to receive and support upon itstop the material to bestitched, the said guide having a groove toreceive the thrum ends and stay-cord and having a cross groove orpassage constituting a guide for the needle, and co-operating with thesaid parts is a thrum-gatherer, the said gatherer being shown ascomposed of two vibrating fingers or arms; but I do not desire to limitmy invention to the exact form of thrum-gatherer shown, as instead ofthe one shown I may use any other usual thrum-gatherer.

My invention consists, essentially, in the combination, insewing-machines for stitching thrum ends, of the followinginstrumentalities, namely: a feeding device to engage the material, aneye-pointed needle and complemental stitch-forming devices, devices toactuate the said feeding and stitch-forming devices to form anoverseaming or zigzag stitch, a work-holder movable longitudinally in aplane at right angles to the plane of reciprocation of the needle andhaving a narrow or thin acting edge, a guide-block having a longitudinalgroove or recess at right angles to the plane in which the needlereciprocates, and thrum-gathering devices, the said work-holderoperating to bend the material into the groove or recess of the saidguideblock, thus enabling the needle at one thrust to enter and pass outfrom the material at the same side and between the right face of thematerial and the stay-cord and thrum ends, the needle at another thrustor descent passing by the material outside the stay-cord and thru [11ends, thus making a stitch to cross and hold the stay-cord and thrumends in place.

Other features of my invention will be hereinafter described in thespecification, and set forth in the claims at the end thereof.

Figure l is a side elevation of a sewingmachine containing myimprovements; Fig. 2, an under side view thereof; Fig. 3, a section ofFig. 1 in the line 00, looking to the left; Fig. 4, a partial top orplan view of the bedplate with the cover-plates removed to show theneedle-bar, shuttle, feed-bar, and guide, said figure also showingclearly the thrumgathering fingers. Fig. 5 is a partial section in theline m, Fig. at. Fig. 6 is a plan view of the shuttle race and carrier,the shuttle being removed; Fig. 7, details of the carrier;'Fig. 8,different views of the shuttle; Fig. 9, the bobbin-case; Fig. 10, thebobbin; Fig. 11, details of the parts co-operating with the needle andshuttle; Fig. 12, an enlarged detail showing the front end of thethrumgathering fingers and their projections; Fig. 13, a top view of thegatherer throat-plate, it having holes through which work the lips orprojections of the gatherer. Fig. 14 shows a plan, side, and end view ofthe guide into which the material is bent by'the work holder or presser;and Fig. 15 is a detail in perspective showing part of the bed-plate andpart of the thrum-gatherer, the presser or holder, and guide-block, withthe material to be stitched placed between the holder and guideblock.

The bed-plate A and the overhanging arm A, together with the lugs A formthe main frame of the machine, the said lugs forming bearings for themain rotating shaft A having fast upon it a cam-hub A, which receives inits cam-groove a roller or other stud,as A extended from the take-uplever X having its fulcrum at A The shaft A has fast upon it a cam 13,which receives in its groove a roller or other stud B at the lower endof a lever B having its fulcrum at B and connected by a suitable pivotor screw, as B, to a slide-bar B which at its front end is suitablyjointed, as at B to a block or slide 13 The block or slide 13 isconnected by suitable pins or connections, as a a, to the fingers orjaws b 11', forming part of the thrumgatherer to be described. Thefinger or jaw b has its fulcrum at 0, while the finger or jaw b has itsfulcrum at c. The fingers or jaws b b are bent or curved down somewhatat their front ends near the guide d and are pro vided with like lips orprojections 2, between which pass the usual thrum ends and staycord, theconnection of the slide-block B with the said fingers or jaws being suchthat during the operation of the machine the fingers or jaws are openedand shut once for each stitch, to thereby gather or collect together andto the stay-cord the thrum ends, the fingers or jaws completing theiroperation upon the thrums and bringing them close to the stay-cord justbefore the 001- lected thrum ends and stay-cord arrive in position abovethe guide d, which sustains the material while the needle e operates.The lips or projections 2 of the thrum-gathering fingers extend upthrough the slots 2 of a plate 102, which I call the gatheringthroat-plate, and in addition to their opening and closing movements thesaid fingers are made to rise and fall with relation to the saidthroat-plate, the said lips or projections rising just before they areclosing to collect the thrum ends to the stay-cord, and vice versa. Theshaft A near the front end of the machine, has fast upon it aworm-toothed gear 0, which engages a worm-toothed pinion C" on a shortvertical shaft 0 which at its upper end carries a crank, pin, orprojection 3, (see Figs. 5 and 11, over which is fitted one end of aconnecting-link 0 which is jointed at C (see Fig. 2) to the needle-bar Cthe latter carrying the needle e. As herein shown, the crank orprojection 3, referred to, receives (see Fig. 5) a stud 4, projectingfrom a link 5, (shown best in Fig. 11,) the said link at its oppositeend engaging a stud 6 at the lowerside of a diskf, (shown in Fig. 5indotted lines and in Figs. 6 and 7,) constituting a part of theshuttle-carrier, the said disk at its upper side having a projection, asf, provided with a hook, as f which enters the space 7 immediately backof the point 8 of the shuttle g, herein shown as substantially circularin shape, the said shuttle having a post 10, which receives upon it thebobbinholder g and bobbin g, the rotation of the shaft 0 rotating theshuttle ina circular race formed in the bed of the machine, theliukmotion described acting, however, to give to the shuttle a variablespeed, so that it will pass through the loop quickly and then moveslowly while the stitch is being drawn up and the needle makes its nextforward movement toward the material.

piece 15, secured to the feed, raising the latter for the properdistance preparatory to each feed movement, the spring 16 depressing thefeed-bar. The feed-bar is cut away centrally, as in Fig. 3, to enablethe link (3 to pass through it.

The guide at (shown separately in plan and end and side view in Fig. 14)is provided with a longitudinal groove (1' (see the end view) and is cutthrough at d for the passage of the usual serrated block h, attached tothe feed-bar, as shown in Fig. 4. The guide is supported at its oppositeends on the bedplate at opposite sides, and the slot covered by theusual cover-plate. The guide has in its bottom alongitudinal groove 20for the usual stay-cord and thrum ends, and a cross-slot, as at 21, toform a throat for the needle e. The guide at has laid upon it alifting-block 22, provided with a stem 23, which extends below theguide, as shown in Fig. 3, in such position that when the feed-bar islifted it meets the said stem and lifts the block 22, the latter in itsascent acting against the under side of and lifting the two fingersorjaws b b, as described.

The head of the machine (see Fig. 1) has bearings for the shank n of thespring-actuated presser or work-holder n, surrounded by a spring, as nso that the said work-holder is normally pressed down against thematerial of the buttonhole-piece lying on the bedplate and over theguide d, the said workholder it normally acting to press the materialinto the groove 11' of the guide cl, so' that the material is bent, asitwere', partially about the work-holder, the stay-cord and thrum endsbeing collected and laid substantially parallel by the thrum-gatheringdevice in front of the bottom of the groove d. The needle e at oneforward thrust is operated to pass into one side of the material,bentover the work-holder, and held bent between it and the guide cland toemerge from the same side of the material and have its loop taken by theshuttle, the

feed at such time being down; but before the next forward thrust of theneedle the feed h rises through the. throat, lifting the material out ofthe groove 01 of the guide andwith it the work-holder, so that theneedle passes close to the materialj ust outside the stay-cord and thrumends, and the loop of needlethread is again locked together with theshuttle or second thread, leaving a thread to cross and bind thestay-cord and thrum ends to the under side of the buttonhole-piece. Theneedle makes two thrusts to each feed-stroke of the feed-bar.

I disclaim the combination, with feeding and also thecombination offeeding and stitchforming mechanism, independent levers pivotallyconnected to the machine and having upwardly-projecting points, a camfor operating said levers to separate the points and to close the leversand compress together the points; also, the combination of feeding andsewing mechanism, a presser-foot, pivoted levers havingupwardly-projecting points, positive means for moving the pointslaterally to open them, automatic means for closing the same, and meansfor pressing upwardly the ends of the said levers, causing them to bearon the material under the machine presserfoot.

In myinvention the stitch forming and feeding mechanism act 'to make anoverseaming stitch and the stitch made is a blind stitch.

I claim- 1. In a sewing-machine for stitching thrum ends, thecombination of the following instrumentalities, viz: a feeding device toengage the material, an eye-pointed-needle and complementalstitch-formin g devices, devicesjto actuate the saidfeeding andstitch-forming devices to form anoverseaming or zigzag stitch, aworkholder movable longitudinally in a plane atright angles to the planeof reciprocation of the needle and having a narrow or thin acting edge,aguide-block having a longitudinal groove or recess within the path ofmovement of the needle and at right angles to the plane in which theneedle reciprocates, and thrumgathering devices arranged in front of theneedle and of the said guide-block, the said work-holder operating tobend the material into the groove or recess of the said guide block,thus enabling the needle at one thrust to enter and pass out from thematerial at the same side and between the right face of the material andthe stay-cord and thrum ends, the needle at another thrust or descentpassing by the material outside the stay-cord and thrum ends, thusmaking a stitch to cross and hold the stay-cord and thrum ends in place,substantially as described.

2. In a sewing machine, stitch forming mechanism, the guide-blockgrooved to receive the material of the buttonhole-piece in the line ofthe stay-cord and thrum ends, the presser foot or holder n, thethrum-gatherer having jaws provided with points, and a feedbar andoperating mechanism therefor, combined with the slot-ted gatherer,throat-plate, and lifting-block to lift the thrum-gatherer and enableits points to rise through the slots in the said throat-plate,substantially as described.

3. In a sewing-machine for stitching thrum ends, the combination of thefollowing instrumentalities, viz; a feeding device to engage thematerial, an eye-pointed needle and complemental stitch-forming devices,devices to actuate the said feeding and stitch-forming devices to forman overseaming or zigzag stitch, a work-holder movable longitudinally ina plane at right angles to the plane of reciprocation of the needle, aguide-block having a longitudinal groove or recess within the path ofmovement of the needle and at right angles to the plane in which theneedle reciprocates, and thrum-gathering devices arranged in front ofthe needle and of the said guide-block, the said work-holder operatingto bend the material into the grooye or recess of the said guide-block,thus enabling theneedle at one thrust to enter and pass out from thematerial at the same side and between the right face of the material andthe stay-cord and thrum ends, the needle at another thrust or descentpassing the material outside the stay-cord and thrum ends, thus making astitch to cross and hold the stay-cord and thrum ends inplace, substantially as described.

4. In a sewing-machine, the rotating shuttle-carrier, the race androtating shuttle, and the horizontally-reciprocating needle-bar andneedle, combined with the link 0 connected directly to the said bar, andthe crank-pin 0 carried by the said shuttle-carrier, to operatesubstantially as described.

5. In a sewing-machine, the bed-plate, a guide-block, a presser orholder to bear upon the material resting upon the guide-block, ahorizontallyreciprocating needle-bar and needle, and a shuttle andshuttle-carrier, and a link to connect the needle-bar andshuttlecarrier, combined with a feed-bar slotted for the passage throughit of the said link, and with a shaft and cams thereon to actuate thesaid feed-bar to move the material after each stitch, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
